Application :tiled May 1, 1924. Serial VNo. 710,465.

@ur invention relates to the class of burners in which petroleum fuelproducts of the heavier grades are employed for heating and similarlpurposes, and an' object of our invention, among others is theproduction of an apparatus that shall be extremely simple inconstruction and particularly eilicient in the results attained byitsoperation.

One form of apparatus embodying our invention and in the constructionand use of which the, objects herein set out, as well as others, may beattained, is illustrated in the accompanying drawings, in which- Figure1 is a top view oi' the base of an oil burner embodying our invention.

Figure 2 is a View in side elevation of the burner as a whole.

Figure 3 is a view in vertical sectionthrough the burner on a planedenoted by the dotted line 3 3 of Figure 1.

Figure 4 is a top view of the' burner. Figure 5 is a detail viewillustrating the construction of one type of wick employed with ourimproved burner.

Figure (i is a view of another type of Wick, having particularadvantages in connection with our improved burner.

Figure 7 is a perspective view of one corner of our improved burnerillustrating the construction thereof. f

Figure 8 is a view, scale reduced, illustrating the arrangement of abattery of our improved burners. I l

ln the accompanying drawings the n`umeral indicates a bur er base thatmay be suitably constructed in any desired Inanner from metal of anyproper kind, this base as a Whole being rectangular in form, asillustrated in Figures 1 and 4; and having main supply passages 16,preferably -oitcruciztorm arrangement, as illustrated in dotted lines inFigure 1 of the drawings, these passages being connected as at thecenter with a main supply pipe 17 leading from a suitable source to behereinafter described.

This improved burner preferably com` of these outlets as may be desiredbeing employed, two of such outlets 2O in the strueture herein shownbeing supplied for the inner burner, and on opposite sides thereof, andfour of the outlets 21 being employed for the. outer burner, suchoutlets being located one at the center of 'each of the four sides ofthe burner and as illustrated in Figure 1 of the drawing. v

Openings 22 are formed through the base 15 in line with each of thepassages 16, as a means for access to such passages for any desiredpurpose, and these openings are closed by means of plugs 23, and asillustrated in Figure 3 of the drawings.

Y Wicks 2li-25 are located in the inner and outer burners, respectively,and these wicks may be of any desired construction, in the formillustrated in Figure 3 each wick comprising an ordinary 'form of wovencotton fabric, or it may be of asbestos. In the form shown in Figure 5an im rov'ed wick comprises two outer layers 26 oi) asbestos or anyother suitable material and an inner supporting member 27 of corrugatedsheet steel or other suitable metal. The form of wick shown in Figure 6comprises a piece of asbestos 28 formed with corrugations'ex-- tendingin the direction of depth of the' Wick, it being understood that all ofthe.

wicks hereinabove referred to will prefer ably extend around the burnerin the groove of which they are located. y

Each ofA the grooves 18 and 19 have widened mouths 29, each terminatingat its bottom in a shoulder 30, upon whichshoulder a burner top issupported. This top comprises an inner 'rectangularly shaped member 31and an outer rectangularly shaped member 32, each of said members,except as to size anda bulged portion in the outer member to behereinafter described, being of the same general formation and adescription of one of said members will, therefore, be understood toapply generally to both ot said members.

These members each comprises 'an outer wall 33 and an inner wall 34 bothformed from sheet metal and having flanges 35 at 'their upper ends, anda cover plate 36 is secured to the upper edge of the inner wall of theinner member 32 tocover the space within and bounded by a said wall,said plate having perforations 38 extending through the plate into saidspace within said inner wall. A. cover plate 37 is similarly secured tothe inner wallof the outer member 32 of the burner and has perforations39 extending through the plate into the space between the two members 3land 32, this plate 37 also having a central opening 40, the edge ofwhich is spaced from the outer edge of the cover plate 36, and as shownin Figure 4 of the drawings.

The cover plates 36 and 37 have lips ile-42 that rest upon the uppersurfaces of the {langes 35 of the inner walls 34, said lips beinglocated on oppositely disposed edges of said plates, and eachof saidplates also has, at its opposite edges, dependin flanges 43-44 thatproject downwardly into the opening bounded by the flanges on the innerwalls 34, and as shown in Figure 3 of the drawings, said cover platesbeing thus held from vertical and horizontal movement.

l The several walls 33 and 34 are spaced a art a distance substantiallyequal to the widt of the mouths 29, and tie-rods 45 extend in op'-lposlte directions through the several walls above described to unitethem in a burner shown a battery of burners arranged in two parallelrows, these burners being evenly spaced apart in all directions andsecured to a base plate 48.

This bulging of the walls acts as a reinforcement to stiffensuch wallsand impart rigidity thereto, and as a further end to this `means ribsmay be formed extending across the walls near their bottom edges, asshown l in Figure 2 of the drawings.

The flanges hereinbefore described located at the tops or mouths of thetubes in addition to acting as-rests and supports for the top 'platesalso serve as stliening means for the tubes.

In accordance with the provisions of the patent statutes we havedescribed the princi ples of operation of our invention, together withthe device which we now consider to represent the best embodimentthereof; but we desire to have it understood that the device shown isonly illustrative, and that the invention may be carried out by othermeans and applied to uses other than thoseabove set out. v

We claim i A burner comprising flue walls arran ed in concentricrelation, burner grooves be tween the walls, horizontal flanges at the uper ends of the fiue walls, concentric cover p ateshaving lip extensionssupported on the flanges of the iiue walls and arranged to allowunobstructed upward passage of heat from the burner grooves, anddownwardly extending flanges on the cover plates located within andcontacting the flanges on said flue walls.
